and 200 µM towards OSCC malign cell lines. Their tumor selectivities were also calculated with two ways. Compound's selectivities towards cancer cell line were found generally low, except compounds bearing 3,4-dimethoxyphenyl 14 (TS1 = 1.3, TS2 = 1.4) and 10 (TS2 = 1.4). All sulfonamide derivatives studied here can be considered as good candidates to develop novel CAs or AChE inhibitor candidates based
合成了4-(3-取代的苯基-5-聚甲氧基苯基-4,5-二氢-1H-吡唑-1-基)苯磺酰胺(9-16),并通过1H NMR,13C NMR和HRMS阐明了它们的化学结构。通过hibrit分子方法,所设计的化合物在单个分子中包括吡唑啉和磺酰胺药效团,这是药物化学中有用的技术,可用于设计对所需的几种生物活性具有有效活性的新化合物。评估了磺酰胺类对人CA同工酶(hCA IandhCA II)和乙酰胆碱酯酶(AChE)酶的抑制能力,并研究了它们对口腔鳞癌(OSCC)细胞系(Ca9-22,HSC-2,HSC- 3,以及HSC-4)和非肿瘤细胞(HGF,HPLF和HPC)。磺酰胺衍生物可抑制胞质hCA I和hCA II同工酶(9-16),Ki值分别在27.9±3.2-74.3±28.9 nM和27.4±1.4-54.5±11.6 nM之间。AChE酶被磺酰胺衍生物强烈抑制,Ki值在37.7±14.4-89
